Thanks for your replies. We definately do not intend to pay any more and are seeing our independant lawyer in Spain in April. There is no certificate of first habitation and I am not convinced that one will be issued until the permanent utilities are in place.
Very sad that this is happening, the gloss has definately gone off the purchase and we now wish we had just kept our motorhome……at least it had battery power for the lights etc!!
It is so disheartening to keep visiting, getting the keys, looking around, then going back to rented accommodation every time.
